How Do Scammers Get Your Number?
If you are receiving frequent spam or scam calls, you may be wondering how fraudsters got access to your phone number in the first place. In reality, there are several common ways your number can end up on marketing lists or in the hands of scammers.
1. Data Breaches
Large companies and online services sometimes suffer data breaches. When customer information is leaked, phone numbers can be included and later sold on the dark web.
2. Online Forms and Competitions
Entering competitions, giveaways, or comparison websites often requires providing a phone number. Some companies share this data with third-party marketing partners.
3. Social Media Exposure
Listing your phone number publicly on social media or business profiles makes it easier for automated systems to collect it.
4. Purchased Marketing Lists
Some organisations legally buy marketing databases. If you previously agreed to marketing contact - even unknowingly - your number may circulate between companies.
5. Number Recycling
Phone numbers are sometimes reassigned by mobile networks. If the previous owner signed up for services, you may receive calls intended for them.
How to Protect Your Phone Number
- Register with the Telephone Preference Service (TPS).
- Enable spam filtering on your smartphone.
- Avoid sharing your number on public websites.
- Read consent boxes carefully before submitting online forms.
- Use a secondary number for online registrations if possible.
